"Oh, mamma, what have you brought?" Such was the cry from all of the Bobbsey twins, as they gathered around Mrs. Bobbsey in the hallway. She had several small packages in her hands, and one looked very much like a box of candy.

Mrs. Bobbsey kissed them all before speaking. "Have you been good while I was gone?" she asked.

Before anything more could be said all were in the dining room and Mrs. Bobbsey was called upon to admire the row of houses. Then the box of candy was opened and each received a share.

"Now you had better go out and play," said the mother. "Dinah must set the table for dinner. But be sure and put on your thick coats. It is very cold and feels like snow."

"Oh, if only it would snow!" said Bert. He was anxious to try a sled he had received the Christmas before.

It was Saturday, with no school, so all of the boys and girls of the neighborhood were out. Some of the girls were skipping rope, and Nan joined these, while Bert went off to join a crowd of boys in a game of football.

"Let us play horse," suggested Freddie to Flossie. They had reins of red leather, with bells, and Freddie was the horse while his twin sister was the driver.

"I'm a bad horse, I'll run away if you don't watch me," cautioned Freddie, and began to prance around wildly, against the grape arbor and then up against the side fence.

"Whoa! whoa!" screamed Flossie, jerking on the reins. "Whoa, you naughty horse! If I had a whip, I'd beat you!"

"If you did that, I'd kick," answered Freddie, and began to kick real hard into the air. But at last he settled down and ran around the house just as nicely as any horse could. Then he snorted and ran up to the water bucket near the barn and Flossie pretended to give him a drink and some hay, and unharnessed him just as if he was a real steed.

Nan was counting while another girl named Grace Lavine jumped, Grace was a great jumper and had already passed forty when her mother called to her from the window.

"Grace, don't jump so much. You'll get sick."

"Oh, no, I won't," returned Grace. She was a headstrong girl and always wanted her own way.

"But jumping gave you a headache only last week," continued Mrs. Lavine. "Now, don't do too much of it," and then the lady closed the window and went back to her interrupted work.

"No—yes," answered Nan. She was so bewildered she scarcely knew what to say. "Oh, isn't it awful!"

They gathered close around the fallen girl, but nobody dared to touch her. While they were there, and one had gone to tell Mrs. Lavine, a gentleman came up. It was Mr. Bobbsey, coming home from the lumber yard for lunch.

"What is the trouble?" he asked, and then saw Grace. "What happened to her?"

Mr. Bobbsey was startled and with good reason, for he had heard of more than one little girl dying from too much jumping. He took the limp form up in his arms and hurried to the Lavine house with it. "Run and tell Doctor Briskett," he called back to Nan.

The physician mentioned lived but a short block away, and Nan ran as fast as her feet could carry her. The doctor had just come in from making his morning calls and had his hat and overcoat still on.

"Oh, Doctor Briskett, do come at once!" she sobbed. "Grace Lavine is dead, and we did it, turning the rope for her!"

"Grace Lavine dead?" repeated the dumfounded doctor.

"Yes! yes!"

"Where is she?"

"Papa just carried her into her house."

Without waiting to hear more. Doctor Briskett ran toward the Lavine residence around which quite a crowd had now collected. In the crowd was Bert.

"Is Grace really dead?" he asked.

"I—I—guess so," answered Nan. "Oh, Bert, it's dreadful! I was turning the rope and she had reached ninety-seven, when all at once she sank down, and——" Nan could not go on, but leaned on her twin brother's arm for support.

"You girls are crazy to jump rope so much," put in a big boy, Danny Rugg by name. Danny was something of a bully and very few of the girls liked him.

"It's no worse than playing football," said a big girl.

"Yes, it is, much worse," retorted Danny. "Rope jumping brings on heart disease. I heard father tell about it."

"I hope Grace didn't get heart disease." sobbed Nan.

"You turned the rope," went on Danny maliciously. "If she dies, they'll put you in prison, Nan Bobbsey."

"I'll see if I can't," answered Bert, and he gave Danny such a look that the latter edged away, thinking he was going to be attacked.

Doctor Briskett had gone into the house and the crowd hung around impatiently, waiting for news. The excitement increased, and Mrs. Bobbsey came forth, followed by Freddie and Flossie, who had just finished playing horse.

"Nan, Nan! what can it mean?" said Mrs. Bobbsey.

"Oh, mamma!" murmured Nan, and sank, limp and helpless, into her mother's arms.

Just then Mr. Bobbsey came forth from the Lavine residence. Seeing his wife supporting their daughter, he hurried in that direction.

"Grace is not dead," he announced. "She had a fainting spell, that is all. But I think after this she had better leave rope skipping alone."
